OK then I'll just hang tinght. I've not seen any response on the email
I sent about 2.6.14-rc5-rt7. I cannot build it. It fails like this:
CC arch/x86_64/kernel/sys_x86_64.o
CC arch/x86_64/kernel/x8664_ksyms.o
CC arch/x86_64/kernel/i387.o
CC arch/x86_64/kernel/syscall.o
CC arch/x86_64/kernel/vsyscall.o
arch/x86_64/kernel/vsyscall.c:57: error: `SEQLOCK_UNLOCKED' undeclared
here (not in a function)
make[1]: *** [arch/x86_64/kernel/vsyscall.o] Error 1
make: *** [arch/x86_64/kernel] Error 2

This is a new failure here since -rc5-rt3.
